Statistical summary of pharmacokinetic parameters obtained from the pharmacokinetic study dosing imepitoin at a nominal dose of 30 mg/kg to six male and female dogs single dose and multiple doses for 4 days under fed and fasting conditions, using a crossover design. Paired comparisons of geometric mean pharmacokinetic parameter were tested for significant difference using t-test. Significantly, different pairs are displayed in bold face. In cases where one parameter was compared (fasted–fed, males–females, day 0–day 5), data are obtained from 12 dogs. In cases where two parameters were compared, data obtained from six dogs were obtained. For two parameter comparison, no statistically significant difference could be obtained.
Pairs of mean in bold differ significantly (P < 0.03).
